W korzystnym zakresie prędkości drgający korpus obsypnika ziemniaczanego charakteryzuje się niższym zapotrzebowaniem energetycznym w stosunku do korpusu sztywnego.

The aim of laboratory research, carried out in a soil bin, was an enegetic evaluation of two different constructions of the section of potato ridger. The section with vibratory frame, held by an elastic conical element, was compared to the traditional section. Three working depths and four velocities of work movement were used. Changes in force demand for pulling and frame vibrations were recorded. The results were analysed stastically. The obtained regression equations described the changes in pulling force in relation to the speed and the working depth. The favourable range of working speed of that frame was in the range of 0.75-1.80 m/s.

A modernised potato ridger, built on the base of the P-447/0 ridger, was an object of the research. In some of its working sections conical springs were used. One of the aims of the research was to obtain information which would make it possible to determine the working resistance of the vibrating ridging body. When the ridger was adequately equipped, a film, with a Panasonic IV video camera, was made during the field examination. The analysis of the film let us determine changes in the position of a special indicator which follows the deflection of the body. This information together with the analysis of the geometry and the active force system, let us determine temporary and mean values of the working resistance of the vibrating ridging body. The work presents results of the analysis of the film which was made at one speed and two depths of the ridger work.
